As I mentioned above, science curriculums follow paths. One's worldview plays heavily on one's interpretation of scientific data. An agnostic, or atheist teaching establishment can become satisfied with one path of scientific theories without searching for others. There may be more to be discovered about thermodynamics, cell structure, irreducible complexity, the decay rate of the earth's magnetic field, radiometric dating, the fossil record, and countless other things that a teaching establishment may not be interested in exploring, if it's comfortable with it's interpretation of current data's indications that the happenstance origins worldview is correct. It goes back to what we touched on before - teaching students HOW to think, not WHAT to think.
